WINDOW-BLIND.

S'PECIPIGATIQN forming part of Letters Patent No. 321,474, dated July '7, 1885.

(No model.)

To aZZ whom it may concern.-

Be it known that I, RUBEN B. AYRES, of the city of St. Louis, State of Missouri, have made a certain new and useful Improvement in Window-Blinds, of which the following is a fuli, clear, and exact description, reference being had to the annexed drawings, in which- Figure 1 is an elevation of shutter or window-blind with part of side rail broken away; Fig. 2, a horizontal section on line 2 8, Fig. 4, (slats open Fig. 3, a horizontal sect-ion on line 23 of Fig. 4,with slats closed; Fig. 4, a vertical section on line 4 4 of Fig. 2; Fig. 5, a vertical section on line 5 5 of Fig. 3; Fig. 6, a detail perspective of end of slat; Fig. 7, a detail perspective of lifting-bar.

In the drawings, A is the shutter frame; a, the slats; a, slat-pivots; m, slat-lugs; (I, bearings in shutter-frame; Y, lifting-bar; 2, slots in lifting-bar, and Q knob or handle attached to liftingbar.

Like letters refer to like parts.

The construction of my invention is as f0llows: On the inside of one of the longitudinal side pieces of the shutter frame-work A is hung a slatlifting bar, Y. This lifting-bar Y is hung or attached to side piece of shutter framework, so as to slide up and down in side piece of framework, preferably fitting into a longitudinal groove in side piece of frame-work, as shown in Figs. 2 and 3. This slat-lifting bar Y is provided with slots .2 z for Slat-lugs ."c to work in. The slats aare pivoted by means of their pivots a and bearings (l in framework side pieces to shutter'frame A, in the usual manner; but to one side of pivots a, at one end of slats a, slats a are provided with lugs :0. These lugs m engage with slots of lifting-bar Y. 0 I preferably attach a knob or handle, Q, to lifting-bar Y, and in any suitable manner, to

provide a ready means of moving lifting-bar Y. This knob Y may also be a thumb screw, to facilitate the adjustment of window-slats at a particular angle.

\Vhen the lifting-barY is raised, the lugs or follow along the line of slots 2 to farther ends of these slots, and thus the slats are opened, (see Figs. 2 and 4,) and when lifting-bar Y is lowered the lugs to drop back along the line of slots z to nearer ends of slots, (see Figs. 3 and 5,) and thus slats are closed.

I am aware that window-blinds having slats pivoted to a stationary plate on the windowframe,and having lugs eccentrically situate on the ends of the slats and fitting in vertical curved slots in a sliding plate, are not new,and

I do not desire to claim the same.

I claim 1. In awindow-shutter, the combination of a frame, A, slats (I, having pivots a, and lugs to, situate on a line with the pivots parallel with the faces of the slats, pivot-bearings (Z, and a lifting-bar having horizontal slots a, substantially as and for the purpose specified.

2. In a window-shutter, the combination of a frame, A, having pivot-bearings d, a sliding bar, Y, fitting in a recess in the frame A, and having horizontal slots 2 and knob Q, and slats a, having pivots to, situate at the middle of the end faces of thesiats, and lugs x, situate on a line with the pivots parallel to the side faces of the slats, substantially as and for the purpose specified.

In testimony whereof I have affixed my signature, in presence of two witnesses, this 18th day of February, 1885.

RUBEN B. AYRES.
